Driving Support Device

Abstract

A driving support device includes: a setting unit configured to set a target parking position; and a support unit configured to: steer, during forward movement of a towing vehicle, a steering unit to a side opposite to the target parking position in a left-right direction of the towing vehicle; then output steering information for steering the steering unit toward the target parking position; and output stop information for stopping the towing vehicle after a connection state between the towing vehicle and a towed vehicle which is towed by the towing vehicle is inclined toward the target parking position.

What is claimed is: 
     
         1 . A driving support device comprising:
 a setting unit configured to set a target parking position; and   a support unit configured to: steer, during forward movement of a towing vehicle, a steering unit to a side opposite to the target parking position in a left-right direction of the towing vehicle; then output steering information for steering the steering unit toward the target parking position; and output stop information for stopping the towing vehicle after a connection state between the towing vehicle and a towed vehicle which is towed by the towing vehicle is inclined toward the target parking position.   
     
     
         2 . The driving support device according to  claim 1 , wherein the support unit controls the steering unit by outputting the steering information. 
     
     
         3 . The driving support device according to  claim 1 , wherein the support unit causes at least one of the steering information and the stop information to be output as an image or sound. 
     
     
         4 . The driving support device according to  claim 1 , wherein the support unit determines whether to switch the towing vehicle from forward movement to backward movement depending on a hitch angle which is an angle between the towing vehicle and the towed vehicle. 
     
     
         5 . The driving support device according to  claim 1 , wherein in a state of causing a display unit to display a setting image including a target parking frame for setting the target parking position, the setting unit receives inclination of the target parking frame, and sets a target parking direction, which is a direction of the towing vehicle at the target parking position, based on the received inclination. 
     
     
         6 . The driving support device according to  claim 5 , wherein the setting unit sets the inclination of the target parking frame rotated in response to the steering of the steering unit as the target steering direction. 
     
     
         7 . The driving support device according to  claim 5 , wherein the setting unit sets the target parking direction by rotating a pair of opposite depth lines included in the target parking frame on the setting image about one ends of the depth lines as respective rotation centers. 
     
     
         8 . The driving support device according to  claim 5 , wherein the setting unit sets the target parking direction by rotating the target parking frame about a first coordinate existing on the setting image. 
     
     
         9 . The driving support device according to  claim 5 , wherein the setting unit sets the target parking direction by receiving, from an occupant, selection of any one of a depth line rotation mode of setting the target parking direction by rotating a pair of opposite depth lines included in the target parking frame about one ends of the depth lines as respective rotation centers on the setting image and a frame rotation mode of setting the target parking direction by rotating the target parking frame about a first coordinate existing on the setting image. 
     
     
         10 . The driving support device according to  claim 6 , wherein the setting unit sets the target parking direction based on steering of the steering unit to the side opposite to the target parking position. 
     
     
         11 . The driving support device according to  claim 5 , wherein, when the target parking direction is set by the setting unit, the support unit outputs the stop information for stopping the towing vehicle when a hitch angle, which is an angle between the towing vehicle and the towed vehicle corresponding to the target parking direction, is reached. 
     
     
         12 . The driving support device according to  claim 1 , wherein the support unit further outputs the stop information for stopping the towing vehicle after a rear end of the towed vehicle advances from the target parking position existing on a side in a left-right direction of the towed vehicle.
